Long-term outcomes of provisional stenting compared with a two-stent strategy for bifurcation lesions: a meta-analysis of randomised trials

Abstract

Background The optimal interventional technique for addressing coronary bifurcation lesions is debatable. Long-term clinical outcomes with provisional stenting (PS) compared with a two-stent (TS) strategy for bifurcation lesions are scarce. We aim to perform the first meta-analysis of randomised controlled trials (RCTs) to explore long-term outcomes comparing both strategies.

Methods An electronic search was performed for online databases until August 2016 for RCTs comparing PS with TS for bifurcation lesions reporting outcomes at 1 year of follow-up or more. Random effects model risk ratios (RRs) were calculated for outcomes of interest.
